This specialty chemical, a diester derived from 1,3-propanediol and oleic acid (also known as PPG-2000DO in some formulations), is primarily used as a plasticizer and softening agent in the production of polymers and plastics. It enhances the flexibility and durability of materials, making it suitable for applications in coatings, adhesives, and sealants. It is also employed in the formulation of lubricants and greases, where it improves viscosity, thermal stability, and lubricity. In the cosmetic industry, it functions as an emollient and conditioning agent in skincare and haircare products, providing moisturizing properties and a smooth texture. Additionally, its bio-based origin from renewable sources supports its use in sustainable materials across various industries.
